New decentralized optimization algorithm promises faster convergence and lower communication costs

By PulseAugur Editorial · [1 sources] ·

A new decentralized optimization algorithm has been developed that integrates variance reduction with multiple local updates. This method offers a stepsize independent of network size and inversely proportional to the number of local updates, allowing for larger stepsizes and faster convergence. The algorithm achieves the first known linear convergence guarantee in expectation for decentralized optimization with multiple local updates under stochastic gradients in a strongly convex setting, while also reducing communication costs by half.

    Variance Reduction for Decentralized Stochastic Optimization with Multiple Local Updates

    arXiv:2610.41927v1 Announce Type: cross Abstract: Multiple local updates are widely used in decentralized optimization to enhance communication efficiency, often in conjunction with stochastic gradients when exact gradient computation is costly. However, such algorithms generally…
